MARCUS LOEWENTHAL, on NEW YORK, N. Y.

BUTTON.

SPECIFICATION forming part of Letters Patent No. 255,640, dated March28, 1882.

Application filed January 19, 188? (No model.)

To all whom it may concern Be it known that I, MARCUS LOEWENTHAL,

of New York, in the county and State of New York, have invented acertain new and useful Improvement in Buttons, of which the following isa specification.

My improvement consists in the combina tion, in a button,of a backpiece,a front piece, a tubular post on theone having-a shoulder at therear end,a rigid shankon the other adapted to enter said post, and aspring or springs attached to said shank at the outer or front end,diverging from the shank rearwardly, and adapted to engage with theshoulder of the post, whereby the front and back pieces may be firmlyunited together and secured to the garment or other article on which thebutton is to be used. Preferably the shank will have a sharp point oredge, so that it may be passed easily through the article on which thebutton is to be used.

In the accompanying drawings, Figure 1 is a perspective view ofa buttonembodying my improvement, the parts being separated and the tubular postbeing shown partly in section. Fig. 2 is a side view of the same withthe parts united, the tubular post and the front piece thereto attachedbeing in section; and Fig. 3 is a perspective view of a button ofmodified form embodying my improvement, the parts being separated andthe tubular post shown partly in section.

Similar letters of reference designate correspending parts in all thefigures.

Referring first to Figs. 1 and 2, A desighates the back piece ofthebutton. It may be made of metal or other suitable material, and hasattached to it, preferably at the central portion, a rigid shank, B,which may also be made of metal or other suitable material. This shank,as here shown, has a sharp point, which will enable it to be inserted ina garment or other article without first piercing the same.

0 is a spring, which is inserted in a hole in the shank near its pointor front end and folded over so as to form two barbs, which have; atendency to move away from the shank and diverge therefrom inwardly.

D designates the front piece, and E designates a tubular post affixedthereto. Both these parts may be made of metal or other suitablematerial, and preferably they will be made integral, as shown. Theinterior of this tubular post is much larger than the shankB; but at therear end there is an inwardly-extending flange, a,- which closely fitsthe shank and forms a shoulder. The point of the shank B is inserted ina garment or other article, F, (see Fig. 2,) and the tubular post E isslipped over it and forced down. As soon as the shoulder of the postpasses the ends of the barbs of the spring the latter move outward andengage with the shoulder, so as to secure the parts together. In thisexample of my invention the shank Bis round as well asthe is fiatinstead of round, and instead of one spring being employed I use twospring-barbs and attach them by rivets, or in any other suitable manner,to the shank. Of course I may here use a single spring, as in theexample of my invention first described. The exterior of thetubularpo'st E of this button is round.

It will be seen that by my invention I produce a very simple, cheap, andeffective button, which can be easily and quickly applied by evenunskilled persons. When its parts are once united they cannot beseparated without breaking one or other of its parts. The end of theshank does not fit tightly in the tubular post. Hence provision isafforded for the lateral yielding of the front piece of the button tothe extent that the article F can be pinched or compressed. If it isdesirable to avoid this, the tubular post may be made to fit the shanksnugly near the tip; or the point of the shank may be made to engagewith the front piece.

What I claim as my invention, and desire to secure by Letters Patent,is'

1. The combination, in a button, of a back piece, a front piece, atubular post on the one having a shoulder at the rear end, a rigid shankon the other adapted to enter the said post, and a spring or springsattached to said shank at the outer end, diverging from said shankrearwardly and adapted to engage with 2. The oombination,in a button, ofa, back 1 having a shoulder at the end, a shank on the piece, a frontpiece, a tubular post on the one having a shoulder at the rear end, arigid sharp-pointed shank on the other adapted to enter said post, and aspring or springs attached to said shank at the point, diverging fromthe shank rearwardly and adapted to engage with the shoulder of thepost, substantially as specified.

3. The combination,in a butt0n,ot' a back piece, a front piece, atubular post on the one other adapted to enter the said post, and aspring inserted in a hole in the shank and fold ed over to form twobarbs adapted to engage 5 M ARC US LOE WENTH AL.
